J E JOHNSON PIPE HANGER. APPLIOATION'FILED JULYBB. 1906- [NVE/VTOR.

Application filed mn- To all whom, it concern.

Be it known-that I, JOHN EMIL JOHNSON, a citizen of the United States, residing at Ishpeming, inthe county'of- Marquette and State of Mi higan, have invented a new and useful Pipe-Hanger, of which the following is a specification.

. This invention has relation to pipe-hangers and it consists in the novel construction and arrangement of its parts, as hereinafter shown and described.

The object of the invention is. to provide a hanger of the nature indicated whichis simple and cheap in construction, easy of-operation and adjustment, and adapted to be readily applied and as readily detached from the wall or other fixed object to which it is attached. The invention consists, primarily, of a screw having a head provid ,-d with a stirrup having a perforation located in alinement with the longitudinal axis of the screw. A .headis located within the stirrup, and a nipple is screw-threaded at one end' into said head. The opposite end of the nipple is screw-threaded, and upon the last said end a bracket of special construction is secured. The said bracket is provided with laterallyextending hooks, which are adapted to enter the-links of a flat chain, and each said hook cooperates With a stop or securing device, also attached to the said bracket for the pur pose of retaining the links positively in engagement with the hooks.

in the accompanying drawings, Figure 1 is a side elevation of the pipe-hanger. Fig. 2 is a vertical sectional view of the same.

The screw 1 is provided with the enlarged integral head 2, from the outer side of which depends the integral stirrup 3. The-surface of saidstirrup is concaved, and the lower portion of the stirrup is providedwith a perfora- 1 threaded into the head tion 4, which is located in alinement with the longitudinal axis of the said screw. A head 5 fits within the said stirrup 3 and the head 2 of the screw 1. v The lower surface of the said head 5 is convex'ed, as at 6, and conforms in contour to the inner surface of the stirrup 3. ,The upper end of the nipple 7 is screw- 5 and extends entirely through the same. The said nipple passes through the perforation 4. The diameter of the perforation 4 is greater than that of the nipple 7. Consequently the said nipple may have a slight universal swing within said perforation. The bracket '8 is screw-threaded upon the lower end of the nip- 4 s thereof, usually adjoin:

slipped sidewi'se into thew-said hook-1.

the operation above described is; reversed. The snap-spring 1 1 is attached to zthebracket 8 and cooperates with the end of the i" hook 9 in retaining the link at the fojt er end of the chain in positive engagement with the said bracket 8. The" chain 12 is preferably of the sprocket type, although any other form of chain which 1s flat and will lie closely against the sides of the pipe 13 may be employed. The '80 said chain 12 passes around the pipe 13 and lies flat against the same, and, as above described, the end links ofthe chain are positively secured in engagement with the hooks 9 9. For difierent sizes of pipe the chain 12 may be lengthened or shortened by adding links to or taking links from the same. The said chain when of the sprocket type is composed-of the usual links, which are engaged with each other by sidewise movement and cannot be disengaged until swung into certain.relations with each other, when the space between the heck of one link and the end thereof will permit of lateral movement of the next adjoining link.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A pipe-hanger com rising an attaching I means having an integra head with an integral stirrup depending therefrom, said stirrup having aperforation, ahead located within the stirrup, a nipple attached to the head Within the stirrup and passing through the stirrup perforation, a bracket attached to the lower end of said nipple and having oppositely-disposed hooks, a chain'linked at its ends upon said hooks, and means attached to the bracket for positively retaining the linked ends of the chain in engagement with said hooks.

2. A pipe-hanger comprising an attaching means having an integral head and an inte- 1 i, i' 's so that the link of a sprocket-chainmayibg when inserted may beswmigdewn and-"can not bedisconnected from-.thcsaid hook until ipposite' gral concaved stirrup the ending therefrom, said stirrup being prov1 ed with a perforation, a head having a convex surface which bears against the concaved surface of said I linked at its 'ends to "said hooks, and means carried by the bracket for positively retaining the links of the chain in engagement with the said hooks. Y

3. 'A pipe-hanger com rising an attaching means having an integra head with an integral'stirrup depending therefrom, a head received within the said stirrup, said stirrup having a perforation, a member attached to said head and passing through said: perforation, a bracket attached to the lower end of said member and having oppositely-disposed 2o hooks, said bracket having at one side a hook located opposite the end of one of the hooks and at its opposite side a snap-sprin bearing 1 against one of said hooks, a chain a apted to be moved sidewise within the space between hook of the bracket and held in engagement therewith by the said snap-spring.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

JOHN EMIL JOHNSON.
